Abstract

Article history Received: 29 January 2021 Accepted: 15 March 2021 Published Online: 30 March 2021 Different sets of dry spell length such as complete series, monthly maximum, seasonal maximum, and annual maximum are applied and modeled with different probability distribution functions (such as Gumbel Max, generalized extreme value, Log-Logistic, generalized logistic, inverse Gaussian, Log-Pearson 3, generalized Pareto) to recognize in which duration, dry spells cause drought. The drought situation and temporal analysis in the North of Iraq region were done using the SPI index and by software of DrinC at a time scale of 3.6 and 12 months. Because of applicability, availability of data and the aim of the study, SPI is selected to analyze the dry spells in this study. Based on the maximum length of the available statistical period, the statistics for the years 1980 to 2019 were used from nine meteorological stations for analysis. The results of the study showed the severity of drought during the study period which related to dry spells. The results of this research confirm the variation of drought occurrence with varying degrees in different time and different dry spells condition in Iraq.

伊拉克北部的干旱和干旱期的影响

文章历史收稿日期:2021年1月29日接收日期:2021年3月15日发布在线日期:2021年3月30日不同的干旱期长度，如完整序列，月最大值，季节最大值和年最大值，应用不同的概率分布函数(如Gumbel Max，广义极值，Log-Logistic，广义logistic，逆高斯，Log-Pearson 3，广义Pareto)进行建模，以识别持续时间，干旱期导致干旱。利用SPI指数和DrinC软件，在3.6个月和12个月的时间尺度上对伊拉克北部地区的干旱情况进行了时间分析。考虑到数据的适用性、可用性和研究的目的，本研究选择SPI来分析干旱期。根据可获得统计期的最大长度，利用1980 - 2019年9个气象站的统计数据进行分析。研究结果表明，研究期间干旱的严重程度与干旱期有关。研究结果证实了伊拉克不同时期、不同旱情条件下不同程度干旱发生的变化。

期刊介绍： The journal provides a focus for the dissemination of new results about the elicitation, representation and validation of requirements of software intensive information systems or applications. Theoretical and applied submissions are welcome, but all papers must explicitly address: -the practical consequences of the ideas for the design of complex systems -how the ideas should be evaluated by the reflective practitioner The journal is motivated by a multi-disciplinary view that considers requirements not only in terms of software components specification but also in terms of activities for their elicitation, representation and agreement, carried out within an organisational and social context. To this end, contributions are sought from fields such as software engineering, information systems, occupational sociology, cognitive and organisational psychology, human-computer interaction, computer-supported cooperative work, linguistics and philosophy for work addressing specifically requirements engineering issues.
